My MPRN number: What is it & Where do I find it?

Meter and a magnifying glass

An MPRN number is a number you may be asked for by ESB or if you are trying to switch electricity supplier online. But what exactly is it, why do we need it and where can you find it? Read on to find out.

What is an MPRN number?

The letters MPRN stand for Meter Point Reference Number. In plain English, the MPRN is an 11-digit reference number that stands for the location your house is connected to the electricity number, your meter.

MPRN numbers are fixed to a certain location, so if you change out your electricity meter, to a smart meter, for example, the MPRN number won’t change. Similarly, if you move home, you will have a new MPRN number.

Each electricity connection has its own individual MPRN number. The first two digits indicate the system operator (usually 10 in Ireland), the next 8 digits are sequentially generated, and the final digit is a “check” digit (which is used to detect simple errors in a series of digits).

How do I find my MPRN number?

electricity meter

The MPRN number is quite a long number, so the majority of people will not know it off by heart. If you have access to any current or previous bills for the property you are living in or moving to, you can find it quite easily.

Depending on which supplier you are with, your MPRN number may be located in different sections of the bill, but it is always labelled MPRN number and followed by eleven digits. Your GPRN number can also be located in the same manner, keeping in mind that a GPRN number is seven, rather than 11, digits.

How do I find my MPRN number without a bill?

If you can’t find any previous bills or have recently moved home and don’t have access to any bills, there are other ways to find out your MPRN number. For rental properties, try contacting the landlord. For purchased properties, try contacting the previous inhabitants. If the property is a new build and part of an estate, the builder should have the number.

If all of the above fails, then you may need to contact ESB Networks. ESB will have your MPRN number stored in the MPRN database under your current or new address. You can contact ESB by calling 021 238 6555 or LoCall 1850 372 757. Representatives are available Monday to Friday from 8:30 a.m. to 6 p.m. and Saturdays from 8:30 a.m. to 1:30 p.m.

If you do not wish to contact ESB Networks by telephone, you can send an email to ESB should respond to your message within two working days.

If you are having difficulty finding your GPRN number and all the above have failed, then you will have to contact Gas Networks Ireland.

Is my MPRN number on my meter?

Unfortunately, your MPRN number is not normally on your meter. Some people may even get confused by looking at their meter and observing that there may be a “meter number” on it.

Is my MPRN the same as my meter number?

The MPRN number refers to the location of a connection to the electricity network, while the meter number usually refers to a serial number of a specific meter. If you call ESB to find out what your MPRN number is, you may be asked to provide the meter serial number (MSN) or the address to help them identify your meter's location.

Note that like your MPRN number, your GPRN number can not be found on the gas meter.

What is a GPRN number?

GPRN stands for Gas Point Reference Number. Like how your MPRN number indicates the location of your home's connection to the electricity network, your GPRN number references where you are connected to the national gas network. You'll need your GPRN number for the following:

  • To switch gas suppliers.
  • To submit gas meter readings to Gas Networks Ireland.

Your gas supplier needs your GPRN number in order to ensure they supply gas to the right connection point.

Where is my gas GPRN?

Your GPRN number is, unfortunately, not located on the gas meter, To find it, look in the top right corner of your energy bill. If you've recently moved in, you can ask the previous owner, your property manager or the landlord for your GPRN number.

How do I find my GPRN number without the bill?

If you don't have a bill, you can get your GPRN number by calling Gas Networks Ireland on 1850 200 694. Gas Networks Ireland is responsible for managing natural gas connections across Ireland. You'll likely need to do this if you've just moved into a new build. This is also who you call if you have a gas leak or emergency.
